| MR |
Title |
Summary |
Merged |
| !6221 |
Add a GitLab branch option to the one-line install script |

Title |
Summary |

Takeaways
-
Small MRs merge fast. Dead-code removals and doc fixes often merged within a day.
-
Write a clear description. Saying what you verified, and what you couldn't, made reviews smoother.
-
Fork pipelines fail for reasons outside your change. Learn to read job logs and explain unrelated failures to reviewers.
-
GitLab reviewers are great. Thanks to every reviewer and maintainer who helped land these.
